[Feature Request] Deform Brush for Contour

[IrvingLu]

What feature or change would you like to see made?

As a physicist, I would like to have a deform tool to perform deformation operations on the contours I have drawn, as shown in the picture.

Why should we prioritize this feature?

RayStation has this feature, which I think is very important for physicists

I have implemented this feature, and if you need it, you can use it directly https://github.com/IrvingLu/cs3d/blob/main/VariationTool
